1. Field of the Invention
The present invention relates to file management methods and systems and, particularly, to a file management method and system for an image capturing device.
2. Description of the Related Art
Current file management systems installed in image capturing devices, such as digital still cameras, only allow checking how much free space remains. The information is not enough for users to properly manage files stored in the image capturing device.
Therefore, it is desirable to provide a file management system and method for an image capturing device, which can overcome the above mentioned problem.
A file management system for managing a number of files stored in an image capturing device includes a classifying unit, a calculating unit, a selecting unit, and a processing unit. The classifying unit is configured for classifying the files in a storage unit of the image capturing device into different clusters according to the file suffixes. The measuring unit is configured for measuring how much memory is currently occupied by the files in the storage unit, size of each cluster and percentage of total available memory occupied by each of the clusters to display the percentages on a display panel. The selecting unit is configured for selecting a desired cluster in response to user input at the input unit. The processing unit is configured for accessing the measurements of the selected cluster(s) and generating a view revealing the measurements on a display panel.
Embodiments of the present file management system and method for an image capturing device will be described in detail below with reference to the accompanying drawings.

The image capturing device 20 includes a storage unit 210, an input unit 220, and a display panel 230. The storage unit 210, such as a memory stick or a SECURE DIGITAL (SD) memory card, is configured for storing the files. These files can be various media files including photos, videos, voices, etc., along with any metadata such as file name, file size, quality, suffix, and timestamp. For example, a photo may be a super fine quality image (2272*1704 pixels), a fine quality image (1600*2000 pixels), a normal quality image (1024*768 pixels), or a basic quality image (640*480 pixels), and suffixed as RAW, JPEG, or TIFF. In addition, a video may be suffixed as AVI or DVI; a voice can be suffixed like MP3 or WMA; and other types of files may include DOC or TXT suffix. All of this information can be stored as metadata of the files. The input unit 220 such as a touch screen is configured for receiving user input. The display panel 230, such as a liquid crystal display (LCD) panel, is configured for displaying various views for users.
The file management system 10 includes a classifying unit 110, a measuring unit 120, a selecting unit 130, and a processing unit 140.
The classifying unit 110 is configured for classifying the files stored in the storage unit 210 according to their suffixes into different clusters, such as “photo cluster”, “video cluster”, “voice cluster”, and “other cluster”.
Further referring to
The selecting unit 130 is configured for selecting a desired cluster in response to user input at the input unit 220. In this embodiment, the photo cluster is selected.
The processing unit 140 is configured for accessing the measurements of the selected cluster(s) and generating a view revealing the measurements on the display panel 230.
